Description

Technical Field

[0001] The utility model belongs to the technical field of trash cans, and in particular relates to an induction trash can with a flip cover that automatically resets. Background Art

[0002] Trash can is a container specially used for holding garbage and waste. In order to prevent the trash can from being left open and odors from spreading, a lid is usually set to close the trash can. The lid opening methods of trash cans with lids include manual lid opening and foot-operated lid opening. Among them, manual lid opening requires direct contact with the surface of the lid by hand, which inevitably touches dirt or bacteria, so it is not in line with the development trend; while foot-operated lid opening is much better than manual lid opening, but it is also inconvenient to use, and it is still not the direction of intelligent development of trash cans.

[0003] With the advancement of technology, it has become a new trend to drive the opening and closing of the trash can lid by motor. In the prior art, a Chinese patent with publication number CN201660257U provides an infrared sensing trash can, including a barrel body and a barrel lid; a sensing device and a driving device are arranged on the front and rear sides of the barrel lid above the barrel body; the sensing device controls the driving device; the driving device drives the barrel lid to perform a flipping action of opening and closing along its flip axis. This patent controls the opening and closing of the trash can lid by setting an infrared sensor to avoid direct contact between human hands and the trash can lid, and eliminates health hazards to a certain extent. However, the induction trash can still has inconveniences in some scenarios. For example: after the lid of the induction trash can is forcibly prevented from closing, it will generally get stuck in a semi-open state, and it is necessary to manually re-control the closure on the interactive board of the trash can, which is not convenient enough and is also prone to health hazards.

[0004] Therefore, in view of the problems existing in the prior art, there is an urgent need to provide a simple and convenient induction trash can structure with automatic flip-top reset. Summary of the invention

[0005] In view of the problems in the related art, the utility model proposes an induction trash can with automatically resetting lid, so as to solve the technical problem that the lid of the induction trash can cannot be automatically reset when blocked by external force.

[0006] The technical solution of the utility model is implemented as follows: an induction trash can with automatic resetting of the flip cover, comprising a barrel body and a barrel head, wherein the barrel head comprises a barrel ring and a barrel cover hinged on the barrel ring; an induction window is arranged on the upper surface of one side of the barrel ring, and an induction module is arranged below the induction window; the induction module transmits or receives an induction signal through the induction window; a motor is arranged on the other side of the barrel ring, and the motor is directly or indirectly connected to the barrel cover for driving the barrel cover to open, hover or close; at least one resetting magnet is arranged on the inner side of the barrel cover, and a Hall sensor corresponding to the resetting magnet is arranged on the barrel ring;

[0007] It also includes a controller, which is electrically connected to the sensing module, the motor and the Hall sensor respectively; when the barrel cover is closed, the reset magnet flips with the barrel cover and approaches the Hall sensor, and cooperates with the Hall sensor by induction; the controller controls the motor to stop or start according to whether the Hall sensor cooperates with the reset magnet by induction.

[0008] In the utility model, the lid of the trash can is reset and closed under the action of the motor. If it is blocked by external force in the middle, the reset magnet on the lid is automatically sensed by the arranged Hall sensor, so as to effectively confirm whether the lid is reset successfully. If it is not reset, the controller controls the motor to start, so as to close the lid, which is reliable and convenient, and avoids direct contact with the lid surface when closing the lid manually, which may cause health hazards.

[0009] As a further improvement of the above solution, the controller, sensing module, and Hall sensor are all arranged on the same side of the barrel ring; the sensing module is an infrared sensing module or an ultrasonic sensing module, and the controller drives the barrel cover to open or close according to whether the sensing signal is received. Integrating the controller, sensing module, and Hall sensor on the same side of the barrel ring can greatly simplify the wiring between these components. The traditional decentralized layout may require complex wiring solutions to connect the various components, which not only increases the difficulty of installation, but also may affect the aesthetics and safety of the barrel ring. The integrated design makes the wiring more concise and direct, reducing the complexity of installation and maintenance.

[0010] As a further improvement of the above scheme, the controller is also connected to a motor state feedback module. When the barrel cover is blocked by external force, the controller receives the stall signal of the motor state feedback module, controls the motor to stop, and keeps the barrel cover in a suspended state. Through the stall signal fed back by the motor, the barrel cover can stop closing and remain in a suspended state at the stop position, avoiding pinching the user's hand and preventing the motor from being blocked by external force and causing damage to the transmission components, thereby extending the service life of the motor.

[0011] As a further improvement of the above solution, the controller is further provided with a timer, and the condition for the controller to drive the lid to close is configured as follows: the Hall sensor does not cooperate with the reset magnet and the duration exceeds a preset time. The timer provides a countdown for the closing of the lid, which can ensure that the lid is automatically reset and avoid the lid being in a stagnant open state for a long time.

[0012] As a further improvement of the above solution, the reset magnet is arranged at one end of the barrel cover away from the hinge and close to the circumferential edge of the barrel cover. Placing the reset magnet at the end away from the hinge means that the magnet can be more accurately aligned with the corresponding Hall sensor when the barrel cover is fully closed, reducing misjudgment caused by deformation of the hinge or incomplete flatness of the barrel cover; at the same time, the reset magnet is located close to the circumferential edge, which helps to ensure that the edge of the barrel cover is fully fitted, further improving the accuracy of detection.

[0013] As a further improvement of the above scheme, the reset magnet is in the shape of a block, a dot or a strip; the inner side of the barrel cover is provided with a position that matches the shape of the reset magnet, and the reset magnet is fixed in cooperation with the position. The setting of the position allows the reset magnet to be directly embedded in these positions, simplifying the installation steps. The staff does not need to use additional tools or complicated fixing methods, but only needs to align the reset magnet with the position and gently push it in. At the same time, the position design ensures that the reset magnet can be accurately installed in the predetermined position, ensuring effective interaction between the reset magnet and the Hall sensor.

[0014] As a further improvement of the above scheme, the barrel ring is provided with a concave step ring groove at the ring mouth, and the step ring groove is adapted to the shape of the barrel cover; the Hall sensor is arranged below the step ring groove, and when the barrel cover is closed, the reset magnet on the inner side of the barrel cover presses against the step ring groove, cooperating with the induction of the Hall sensor.

[0015] As a further improvement of the above solution, a plurality of buffer pads are provided on the circumferential edge of the inner side of the barrel cover, and the barrel cover abuts against or separates from the upper end surface of the stepped ring groove through the buffer pads. The buffer pads provide a buffer for the closing of the barrel cover, avoiding the barrel cover from rigidly abutting against the barrel ring, which helps to extend the product life and improve the actual use experience of users.

[0016] As a further improvement of the above solution, the output shaft of the motor is drivingly connected to a swing arm, a push rod is hinged on the swing arm, and the other end of the push rod is drivingly connected to the barrel cover.

[0017] As a further improvement of the above solution, the barrel ring is provided with a plurality of status indicator lights near the sensing window, and the status indicator lights are electrically connected to the controller to display the current open / closed state of the trash can lid. The setting of the status indicator lights can clearly feedback the state of the trash can lid, so that the user can perform the next operation on the trash can.

[0018] Beneficial effects of the utility model:

[0019] The lid of the induction trash can is reset and closed by the motor. If it is blocked by external force, the Hall sensor automatically senses the reset magnet on the lid to effectively confirm whether the lid is reset successfully. If it is not reset, the controller controls the motor to start and close the lid, avoiding direct contact with the lid surface when closing the lid manually, which may cause health hazards. At the same time, the motor can drive the lid to open, hover or close. When it is in the hovering state, it can effectively avoid pinching the user's hand and extend the service life of the motor.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-Figure 6 As shown, a sensor trash can with automatically resetting flip lid comprises a body 2 and a head 1, wherein the head 1 comprises a ring 11 and a lid 12 hinged on the ring 11; a sensing window 111 is provided on the upper surface of one side of the ring 11, and a sensing module 112 is provided below the sensing window 111; the sensing module 112 transmits or receives a sensing signal through the sensing window 111;

[0035] A motor 3 is provided on the other side of the barrel ring 11, and the motor 3 is directly or indirectly connected to the barrel cover 12 for driving the barrel cover 12 to open, hover or close. In this embodiment, the output shaft of the motor 3 is driven and connected to a swing arm 31, and a push rod 32 is hinged on the swing arm 31, and the other end of the push rod 32 is connected to the barrel cover 12.

[0036] A reset magnet 121 is provided on the inner side of the barrel cover 12, and a Hall sensor 113 corresponding to the reset magnet 121 is provided on the barrel ring 11; when the barrel cover 12 is closed, the reset magnet 121 flips with the barrel cover 12 and approaches the Hall sensor 113, and senses and cooperates with the Hall sensor 113; the controller 4 controls the motor 3 to stop or start according to whether the Hall sensor 113 senses and cooperates with the reset magnet 121.

[0037] In this embodiment, the reset magnet 121 is arranged at one end of the barrel cover 12 away from the hinge, and is close to the circumferential edge of the barrel cover 12, and is centrally arranged. Placing the reset magnet 121 at the end away from the hinge means that the magnet can be more accurately aligned with the corresponding Hall sensor 113 when the barrel cover 12 is fully closed, reducing misjudgments caused by deformation of the hinge or incomplete flatness of the barrel cover 12; at the same time, the reset magnet 121 is located close to the circumferential edge, which helps to ensure that the edge of the barrel cover 12 is fully fitted, further improving the accuracy of detection.

[0038] The reset magnet 121 is in the shape of a block, a dot or a strip; specifically, the shape of the reset magnet 121 is preferably a circular block, and the area of ​​the reset magnet 121 can be slightly larger than the sensing end of the Hall sensor 113 to improve the sensing accuracy and efficiency. The inner side of the barrel cover 12 is provided with a clamping position 122 that matches the shape of the reset magnet 121, and the reset magnet 121 is fixed in cooperation with the clamping position 122. The setting of the clamping position 122 allows the reset magnet 121 to be directly embedded in these clamping positions 122, simplifying the installation steps. The staff does not need to use additional tools or complicated fixing methods, but only needs to align the reset magnet 121 with the clamping position 122 and gently push it in. At the same time, the design of the clamping position 122 ensures that the reset magnet 121 can be accurately installed in the predetermined position, ensuring the effective interaction between the reset magnet 121 and the Hall sensor 113.

[0039] In this embodiment, the barrel ring 11 is provided with a concave stepped annular groove 114 at the ring mouth, and the stepped annular groove 114 and the barrel cover 12 are adapted to each other in shape; the Hall sensor 113 is provided below the stepped annular groove 114, and when the barrel cover 12 is closed, the reset magnet 121 on the inner side of the barrel cover 12 presses against the stepped annular groove 114, and cooperates with the Hall sensor 113 inductively. More specifically, buffer pads 123 are provided at the edges of both sides of the barrel cover 12, and the barrel cover 12 abuts against or separates from the upper end surface of the stepped annular groove 114 through the buffer pads 123. The buffer pads 123 provide a buffer for the closing of the barrel cover 12, avoiding the rigid collision between the barrel cover 12 and the barrel ring 11, which helps to extend the product life and improve the actual user experience.

[0040] It also includes a controller 4, which is electrically connected to the sensing module 112, the motor 3 and the Hall sensor 113 respectively; in this embodiment, the controller 4, the sensing module 112 and the Hall sensor 113 are all arranged on the same side of the barrel ring 11; integrating the controller 4, the sensing module 112 and the Hall sensor 113 on the same side of the barrel ring 11 can greatly simplify the wiring between these components. The traditional decentralized layout may require a complex wiring scheme to connect the various components, which not only increases the difficulty of installation, but also may affect the aesthetics and safety of use of the barrel ring 11. The integrated design makes the wiring more concise and direct, and reduces the complexity of installation and maintenance. The sensing module 112 is an infrared sensing module 112 or an ultrasonic sensing module 112, and the controller 4 drives the barrel cover 12 to open or close according to whether the sensing signal is received. Specifically, the sensing module 112 of this embodiment adopts an infrared sensing module 112.

[0041] In this embodiment, the controller 4 is also connected to a motor state feedback module. When the bucket cover 12 is turned over and blocked by external force, the controller 4 receives the stall signal of the motor state feedback module, controls the motor 3 to stop, and keeps the bucket cover 12 in a suspended state. Through the stall signal fed back by the motor 3, the bucket cover 12 can stop closing and keep in a suspended state at the stop position, avoiding pinching the user's hand and preventing the motor 3 from being blocked by external force and causing damage to the transmission components, thereby extending the service life of the motor 3.

[0042] Specifically, the motor state feedback module can be an encoder, which is connected to the output shaft of the motor 3 and connected to the controller 4. When the motor 3 works normally, the encoder outputs a pulse signal and transmits it to the controller 4; when the closing of the barrel cover 12 is blocked by external force, the motor 3 is blocked, and the controller 4 reads the interruption information of the encoder pulse signal, and the controller 4 controls the motor 3 to stop, so that the barrel cover 12 stops closing and keeps it in a hovering state at the stop position.

[0043] The motor state feedback module can also be a current detection module. When the closing of the barrel cover 12 is blocked by external force, the motor 3 is blocked. At this time, the current signal suddenly changes. The current detection module reads the current signal of the motor 3 when it is blocked and transmits it to the controller 4. The controller 4 controls the motor 3 to stop, so that the barrel cover 12 stops closing and remains in a suspended state at the stop position.

[0044] In this embodiment, the controller 4 is also provided with a timer, and the controller 4 drives the barrel cover 12 to close under the following conditions: the Hall sensor 113 does not cooperate with the reset magnet 121, and the duration exceeds the preset time. The timer provides a countdown for the closing of the barrel cover 12, which can ensure that the barrel cover 12 is automatically reset and prevent the barrel cover 12 from being in a stagnant open state for a long time. Specifically, the timer stores a first time threshold M1 and a second time threshold M2. When the barrel cover 12 is opened, the timer starts counting, and when the timing time reaches the set first time threshold M1 (such as 5 seconds), the controller 4 controls the shaft of the motor 3 to rotate and drive the barrel cover 12 to close; when the barrel cover 12 is blocked by external force and hovers when closed, the timer starts counting, and when the timing time reaches the set second time threshold M2 (such as 3 seconds), the controller 4 controls the shaft of the motor 3 to rotate and drive the barrel cover 12 to close.

[0045] The barrel ring 11 is provided with a plurality of status indicator lights near the sensing window 111, and the status indicator lights are electrically connected to the controller 4 and are used to display the current open / closed state of the trash can lid 12. The setting of the status indicator lights can clearly feedback the state of the trash can lid 12, so that the user can perform the next operation on the trash can.

[0046] Through the above scheme of the utility model, in specific applications: the lid 12 of the trash can is reset and closed under the action of the motor 3. If it is blocked by external force in the middle, the controller 4 receives the stall signal of the motor state feedback module, controls the motor 3 to stop, and keeps the lid 12 in a suspended state to avoid pinching the user's hand and prevent the motor 3 from being blocked by external force and causing damage to the transmission parts, thereby extending the service life of the motor 3. In addition, the Hall sensor 113 automatically senses the reset magnet 121 on the lid 12, which can effectively confirm whether the lid 12 is reset successfully; if it is not reset, the controller 4 controls the motor 3 to start, thereby closing the lid 12, which is reliable and convenient, and avoids direct contact with the lid surface when closing the lid manually, which causes health hazards.

[0047] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
